Community‐informed and codesigned research to understand the impacts of railways on wildlife
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

A Study on the Birds Diversity and Vertical Distribution of Wuyi Mountains in Fujian [PDF]
, 2017 武夷山脉位于中国江西省、福建省两省边境。北接仙霞岭，南接九连山，呈东北-西南走向。长约550km，平均海拔1000m左右。特殊的地理位置和良好的生态环境使其保存了世界同纬度带最完整、最典型、面积最大的中亚热带原生性森林生态系统。国内外学者很早就开始对福建武夷山脉的鸟类进行调查和研究，研究范围仅限于单独的保护区，缺少整个范围的调查和研究。 笔者于2015年5月至2016年12月采用样线法和红外相机对分布在福建武夷山脉上的4个国家级自然保护区 ...

Research on General Algorithm and Software Implementation of Fiber Laser [PDF]
, 2013 结合激光速率方程理论和光纤激光器中信号光与泵浦光的传播方程,提出了适用于线型腔、环形腔光纤激光器的通用的行波理论模型,可以模拟连续波(COnTInuOuS WAVE,CW)、主动/被动调Q脉冲输出。本模型考虑到了传统的点模型(POInTMOdEl)无法计算的因素,主要包括泵浦光和信号光在腔内分布不均匀的特性,以及传输、连接等不同损耗和非掺杂光纤对激光的影响,因此具有较高的理论精度。通过有限差分方法(fInITE dIffErEnCE METHOd,fdM)推导出了求解光纤激光器行波模型的数值算法 ...
